Black square over screen

text was turned On I suspect.

Is closed caption turned on? (and the channel doesn't have any captions) Turn it off.

If it is a large black rectangle that blots out the middle of the screen then you need to check your CC (closed caption) setting. Make sure the closed caption is turned off. I'm not up to date on the newer sets, but a lot of the older ones had more than one CC setting. One setting ran the captioning across the bottom, another put it in a big black box in the center of the screen. Most places didn't support the full text so all that showed was a big black rectangle on the screen. Since I'm not sure exactly what your rectangle looks like, this is my best estimate of your problem. Hope this helps.

turn off close caption

Just use your remote or the tv menu to turn off closed captioning.

go into your menu and access the closed caption modes. someone has accidently put your tv in the "text" mode. turning off the closed caption feature will correct this.

unplug the set for a while , but this problem will return because of a malfunction in the EPROM CHIP , this controls the menu and a few other functions

try the closed caption adjustments. i had a tv that did the same thing and the captiong did it. turn caption off nd try.

I hit the freeze button and it came offf

Shut off the closed captioning and your problem will be gone.
